A laboratory ultracentrifuge is designed to produce a centripetal acceleration of 4.0 106 g at a distance of 5.00 cm from the axis. What angular velocity in rev/min is required?

Require R*w^2 = 4*10^6 g

Then solve for w, which will be in radians per second.

Then convert w to rpm.

Use an ^ before your exponents

R = 0.05 m

g = 9.8 m/s^2

Thank you drwls...

I got 2.7e6 but apparently that is incorrect.
